Ross P. Cameron argues that the flow of time is a genuine feature of reality, and defends a version of the Moving Spotlight theory: the view that past and future beings are real, but there is nonetheless an objectively privileged present. He goes on to defend an account of the open future: what will happen is, as yet, undetermined. it's well worth the read because, even if you come away from the book holding onto the same view of time as you had going in, you will certainly learn something along the way ... I do think Cameron has breathed new life into the view, and getting on the roller coaster of The Moving Spotlight is a ride well worth taking.
